SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Use when building complex business domains in Spring Boot applications. It prevents anemic domain models by guiding the creation and interaction of aggregates, value objects, and domain events, aligning code with real domain concepts.

Core Features & Use Cases

Aggregates: enforce boundaries and root-centric access.
Value Objects: immutable, equality by value with invariants.
Domain Events: capture intent and publish after state changes.
Anti-Corruption Layer (ACL): isolate external models from domain.

Quick Start

Define your first domain aggregate with clear boundaries and value objects, then apply the Domain-Driven Design rules above.

FAQPage Schema

How do I prevent an anemic domain model in Spring Boot?▼

To prevent an anemic domain model in Spring Boot, design rich domain models by enforcing aggregate boundaries, immutability for value objects, and domain event handling. This replaces anemic CRUD patterns by aligning code directly with complex business rules and real domain concepts.

When do I need an anti-corruption layer in domain-driven design?▼

You need an anti-corruption layer in domain-driven design when integrating external models or subsystems. It isolates external models from your domain, ensuring that external dependencies do not corrupt your core domain logic and preserving the integrity of your bounded contexts.

How do I implement aggregates and value objects in a Spring Boot application?▼

Implement aggregates in Spring Boot by enforcing root-centric access and strict boundaries. Define value objects as immutable entities with equality determined by value, ensuring invariants are maintained within the aggregate to support complex business rules consistently.

What is the best way to handle domain events across bounded contexts?▼

The best way to handle domain events across bounded contexts is to capture intent and publish events after state changes. This approach ensures aggregate consistency and maintains clear boundaries between different domain segments within complex Spring Boot applications.

Does domain-driven design work for simple CRUD applications?▼

Domain-driven design is not suited for simple CRUD applications. It is designed specifically for projects with complex business rules, multiple aggregates, and domain events, where enforcing rich domain models prevents the limitations of anemic CRUD patterns.
